the saleen wheels are for the f150's like yours...completely different bolt pattern and not like mine and bama's where the only thing I would need to d to swap over is grab a drill (not sure right off hand what the size was...that's how alot of people get the 2nd gen wheels on the 1st gen's...learned that when lookin for replica's)
I think a 23 would be too big for a Lightning personally. The biggest wheel I'd run on a L is a 20. Those 23's look spot on when mounted up on 04-08's.
